Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus, and more particularly to a document processing apparatus that controls a scroll amount of display information displayed in each display area of a display unit for each display area. .

(Prior art)

In general, many document processing apparatuses such as electronic typewriters for English have a relatively small liquid crystal display capable of displaying two or several lines of characters and symbols.

This small display is configured to be able to display display information such as words, phrases and sentences. If the length of one line of this display information is longer than the number of digits that can be displayed on the display, use the scroll key. The display information is scrolled by operating. In this case, the display information of all the rows is simultaneously and simultaneously scrolled in the same direction.

[Problems to be solved by the invention]

By the way, for example, in an English document processing apparatus having a small liquid crystal display capable of displaying two lines, when different types of information are simultaneously displayed on the first line and the second line, the forward scroll key is operated to operate these keys. When the display information is scrolled forward in the head direction of the display data, the display information is scrolled simultaneously regardless of the amount of information (the length of the information). Therefore, when the end of the long display information is displayed, There is a problem that the short display information is hidden, and the backward scroll key must be operated to display the hidden short display information, and the scroll operation becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a document processing apparatus capable of automatically controlling the scroll amount of display information displayed in each display area for each display area according to the length of the display information.

[Means for solving the problem]

As shown in the functional block diagram of FIG. 1, the document processing apparatus according to the present invention includes input means for inputting characters, symbols, and various command signals, and a plurality of display areas of one or more lines. Display means, a plurality of display data memories for respectively storing display data of characters and symbols to be displayed in each display area, and a plurality of display control sections for reading data of each display data memory and displaying the data in a corresponding display area And a plurality of display control units for scrolling the characters or symbols displayed in the plurality of display areas in the head direction or the end direction of the display data in response to the operation of the scroll command key. And determining whether the last or first display data has been displayed for each of the plurality of display data memories during the operation of the scroll control means. Instruct the display control unit corresponding to the display data memory in which the display data is displayed to stop scrolling, and instruct the display control unit corresponding to the display data memory in which the final or first display data is not displayed to be displayed. And a scroll stop means for instructing to continue scrolling.

[Action]

In the document processing apparatus according to the present invention, data in the display data memory corresponding to each display control unit of the display control means is read and displayed in the display area of the corresponding display means. When the scroll key is operated in this state, the scroll control means instructs each display control unit to scroll the characters or symbols displayed in the display area in the head direction or the tail direction of the display data. At this time, the scroll stop means determines whether or not the last or first display data is displayed for each of the plurality of display data memories, and a display control unit corresponding to the display data memory on which the last or first display data is displayed. Is instructed to stop scrolling, and the display control unit corresponding to the display data memory in which the last or first display data is not displayed is instructed to continue scrolling.

〔The invention's effect〕

According to the document processing device of the present invention, by providing the display control means, the scroll control means, the scroll stop means, etc., the final display data or the first display data is displayed for the display data of each display data memory. At times, scrolling is automatically stopped for the display control unit corresponding to the display data memory even during scroll control, so that the end portion or the head portion of the long display information and the short display information can be displayed simultaneously by aligning the scroll operation. Can be greatly simplified.

In the program memory of the ROM 17, a control program for controlling the display mechanism DM corresponding to the code data input from the keyboard 3, a control program for storing the code data in the input data buffer 21, and a cursor movement key are operated. And a word alert processing control program for executing word alert processing on document data stored in the input data buffer 21.

The word alert processing control program stores a word alert processing subroutine, a scroll control subroutine, and a scroll stop subroutine.
Note that the word alert processing is a known one, and will be briefly described. For example, any of words having similar pronunciations and being easily confused, such as the words “to”, “too”, and “two”, is detected in the document data. Sometimes it warns or displays similar words.

In the dictionary memory of the ROM 18, for example, the words "to", "to
A large number of word groups obtained by grouping a plurality of words having similar pronunciations such as "o" and "two" and easily confused, and their part of speech and meaning are stored in association with each other. Here, it is referred to as explanation data including part of speech and meaning.

The input data buffer 21 of the RAM 20 stores two lines of display data input from the keyboard 3 and displayed on the display 10 when inputting document data.

The cursor pointer 22 stores one address in the input data buffer 21 corresponding to the cursor display position. This content is used as a cursor pointer KP.

The input word data memory 23 (which corresponds to the display data memory) stores a second word on the display 10 when a similar word whose pronunciation is similar to the input word is detected.
The word data of the input word and its description data are read from the dictionary memory 18 and stored as display data for display in the display area E2.

The similar word data memory 24 (corresponding to a display data memory) stores word data of similar words detected by the word alert processing and their explanation data to be displayed in the first display area E1 of the display 10. The data is read from the dictionary memory 18 and stored as display data.

The first address pointer 25 has a similar word data memory
The start address (the contents are referred to as a pointer TA1) and the end address (the contents are referred to as a pointer EA1) of the display data stored in 24 are stored.

The second address pointer 26 has an input word data memory
The start address (the content is referred to as a pointer TA2) and the end address (the content is referred to as a pointer EA2) of the display data stored in 23 are stored.

The first display data pointer 27 is the address of the similar word data memory 24, which is the address of the display data at the head display position of the display data displayed in the first display area E1 of the display 10 (the contents are referred to as the pointer TCP1). ) And the address of the end display position (the contents are referred to as a pointer ECP1) are stored.

The second display data pointer 28 is an address of the input word data memory 23, which is the address of the display data at the head display position of the display data displayed in the second display area E2 of the display 10 (the contents are referred to as the pointer TCP2). ) And the address of the display data at the end of the display position (the content is referred to as a pointer ECP2).

Next, the routine of the word alert processing control performed by the control device C of the word processor 1 will be described with reference to the flowcharts of FIGS. 4 (a) to 4 (c).
In the drawing, Si (i = 1, 2, 3,...) Is each step.

Each time various keys such as a character key and a space key are operated on the keyboard 3, the code data corresponding to the key is stored in the input data buffer 21 and this control is started at the same time, and the space key and the return key are started. When the word separation key is operated (S10: Yes), the word data of the input word indicated by the cursor is read out in the input data buffer 21 based on the cursor pointer KP (S11), and the input word is processed by the word alert processing subroutine. Is searched in the dictionary memory of ROM18 (S1
2) When similar words are searched (S13: Yes), similar word display processing control is executed (S14). When a key other than the delimiter key is operated (S10: No), this control ends and the process returns to the main routine. When the display processing control (FIG. 4 (b)) is started, the similar word data detected from the dictionary memory of the ROM 18 and its description data are read out and stored in the data memory 24 as display data (S20). The head address of the display data in the data memory 24 is stored in the address pointer 25 as the pointer TA1, and the tail address is stored in the address pointer 25 as the pointer EA1 (S
21), the pointer TA1 is stored in the data pointer 27 as the pointer TCP1, and the address obtained by adding D to the pointer TCP1 is stored in the data pointer 27 as the pointer ECP1 (S22). Here, D is the value of the number N-1 of displayable digits in the first display area E1 of the display 10. The number N of displayable digits in the first display area E1 and the second display area E2 is the same. Note that these pointers TA1, E
FIG. 5 shows the relationship among A1, TCP1, and ECP1.

Next, input word data of the read input word and RO
Descriptive data corresponding to the input word read from the dictionary memory of M18 is stored in the data memory 23 as display data (S23), and predetermined addresses of the data memory 23 are stored in the respective pointers TA2, EA2, TCP2, and ECP2. (S24 ・ S2
5) Based on each of the pointers TCP1, ECP1, TCP2, and ECP2, a similar word and its description are displayed in the first display area E1 of the first display line of the display 10, and the second display line of the second display line is displayed. The input word and its description are displayed in the display area E2 (S26). However, the amount of display data consisting of the similar word data read in this control and its description data is the first.
It is assumed that the number of displayable digits in the display area E1 is larger than the number of displayable digits in the second display area E2. For example, as shown in FIG. 6, at the left end of the second display line of the display 10, a description "ALERT W" of the input word display is displayed, and in the second display area E2, the input word "their" and its input word "their" are displayed. An explanation is displayed. However, the display data “e) belonging to them” at the end of the description is not displayed. Further, at the left end of the first display line, a description sentence “SUGGEST” of similar word display is displayed, and the first display area E
1 displays a similar word "they're" similar to the input word and its description. However, the display data “are” at the end of the description is not displayed.

When the replacement key is operated (S27 / S28: Ye
s) If a similar word can be input (replaceable) in the display line (S29: Yes), the input word data is replaced with similar word data in the input data buffer 21 (S30), and the document data is displayed ( S31), end this control and return. However, when the forward scroll key is operated (S27 / S33: Yes), when the pointer ECP1 is not equal to the pointer EA1, that is, when the end data of the display data in the data memory 24 is not displayed in the first display area E1 ( S3
4: No), each of the pointers TCP1 and ECP1 is incremented by one (S35), and information scrolled forward by one digit is displayed in the first display area E1 based on each of the pointers TCP1 and ECP1 (S36). Further, when the end data of the display data in the data memory 23 is not displayed in the second display area E2 (S3
7: No), each of the pointers TCP2 and ECP2 is incremented by one (S38), and information scrolled forward by one digit is displayed in the second display area E2 based on each of the pointers TCP2 and ECP2 (S39). Here, when the end data of the data memory 24 is displayed in the first display area E1 and the end data of the data memory 23 is not displayed in the second display area E2 (S34: Ye
s, S40: No), only the display information in the second display area E2 is scrolled forward by S38 and S39, and the end data of the data memory 24 is not displayed in the first display area E1 and the data is displayed in the second display area E2. When the tail data of the memory 23 is displayed, only the display information of the first display area E1 is scrolled forward (S34: No, S35 / S36, S37: Yes). Further, when the tail data of the display data is displayed in both display areas E1 and E2 (S34 and S40: Yes), the buzzer 12 is sounded (S41).

On the other hand, when the backward scroll key is operated (S2
7 ・ S42: Yes) Since the scroll direction is only different from that when the forward scroll key is operated, the brief description is that the first data of the display data is displayed in the first display area E1 and the second display area E2. If not, the information scrolled backward by one digit is displayed in both display areas E1 and E2 (S43 to S48). When the first data is displayed in the first display area E1 and the first data is not displayed in the second display area E2, only the display information of the second display area E2 is scrolled backward. When the first data is not displayed in the first display area E1 and the first data is displayed in the second display area E2, only the display information of the first display area E1 is scrolled backward (S43: No, S44 and S45, S46: Yes). Further, when the head data of the display data is displayed in both display areas E1 and E2 (S44 and S49: Yes), the buzzer 12 is sounded (S4).
1). For example, when the forward scroll key is operated a plurality of times in the display state shown in FIG. 6, as shown in FIG.
The first display area when the forward scroll key is operated three times
When the forward scrolling of the description of the similar word of E1 is stopped, and then only the description of the input word in the second display area E2 is scrolled forward, and then the end data “m” is displayed in the second display area E2. Buzzer 12 sounds.

Next, when the next candidate key is operated (S27 / S50), if there is a next similar word in the dictionary memory 18, the similar word data and its description data are read out and stored in the data memory 24 (S51). : Yes ・ S52), each pointer as in S21 ・ S22
A predetermined address is stored in TA1, EA1, TCP1, and ECP1 (S5
3. S54) Further, a predetermined address is stored in each of the pointers TCP2 and ECP2 so that the head of the display data is displayed in the second display area E2 (S55), and the next similar word is stored in the first display area E1. And its description are displayed, and the second display area
The input word and its description are displayed in E2 (S56).

Next, when the cancel key is operated (S27 / S
57: Yes), and returns after displaying the document data. still,
Buzzer sounds when a key other than the replacement key, forward / reverse scroll key, next candidate key, and cancel key is operated
12 is sounded (S41).

As described above, the first display area E1 or the second display area in which the first data or the last data of the display data is displayed.
Since the scrolling of the display information of E2 is automatically stopped,
The long display information and the short display information can be displayed simultaneously with their trailing end portions aligned, and the scroll operation can be greatly simplified.

Note that the similar word display control is partially changed, and the end area of the display data is already displayed in the display area E1 or
With respect to E2, it is also possible to configure so that the display information is not scrolled from the beginning.

The present invention is applicable to a word processor having a display in which each of the display areas E1 and E2 includes a plurality of rows.

Various word processors, a spell checker, and a scheduler (schedule) having a spell check function and displaying the detected misspelled word and a plurality of candidate words of the misspelled word in different display areas of the display. The present invention can be applied to various word processors having functions.

Of course, the present invention can be applied to various document creation devices such as a European word processor and a Japanese word processor having a floppy disk drive device and storing document data on a floppy disk.
